I have a light green algae on my substrate. I recently purchased a Sea Grass Wrasse a few weeks ago and he burrows deep. This algae problem started around that time. I have another factors have changed too. I am down to 4 50/50 PC 96 watt lights from 6 because of dead ballast. I change about 20 gal every week. I still do not use RODI yet but use highly purified water.
I will upload pic soon.
